> Somehow in the datasheet, the third sentence in section > 6.6 (1) seems to contradict the previous statements Neil, DS41250F says, in 6.4, - The Timer1 oscillator is shared with the system LP oscillator. Thus, Timer1 can use this mode only when the primary system clock is derived from the internal oscillator or when in LP oscillator mode So I infer from that you can have the whole chip running at 32k (LP) or the core at IntRC and T1 at 32k -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
